Editor's note: This week's edition of "Office Hours" comes in 140-character bits on Twitter, where Melissa wrote them earlier this evening. After Melissa's appearance today on "Politics Nation with Al Sharpton," some critics tweeted at her, taking issue with her quote:
"Although race is the main strategy being used as the criticism of President Obama, I actually don't think that racism is the reason that Republicans are criticizing the President."
The tweets below are presented in order, and her full segment tonight on "Politics Nation" embedded after the jump. You can view Melissa's Twitter feed here. -- JS
